Update value of a nested dictionary of varying depth

by

I’m looking for a way to update dict dictionary1 with the contents of dict update wihout overwriting levelA

dictionary1={'level1':{'level2':{'levelA':0,'levelB':1}}}
update={'level1':{'level2':{'levelB':10}}}
dictionary1.update(update)
print dictionary1
{'level1': {'level2': {'levelB': 10}}}

I know that update deletes the values in level2 because it’s updating the lowest key level1.

How could I tackle this, given that dictionary1 and update can have any length?
